In this paper we consider the class of equations $u_{tt}=f(x,t,u,u_x,u_t)u_{xx}+g(x,t,u,u_x,u_t)$. We derive equivalence transformations and we classify differential invariants.

Abstract
In this paper we consider the class of equations $u_{tt}=f(x,t,u,u_x,u_t)u_{xx}+g(x,t,u,u_x,u_t)$. We derive equivalence transformations and we classify differential invariants.File in questo prodotto:
